A year-long investigation has revealed the disturbing log transcript of communications between the doomed Titan submersible and its mothership — a document that was circulated by millions online — was completely fake.

The logbook claimed to detail the final communications between the submersible, which was attempting to reach the Titanic with five voyagers on board, and the mothership.

There was widespread suspicion when the log documents were released last year, with many questioning whether the transcript between the two vessels was legitimate.

According to the New York Timesthe head of the US government team investigating the disaster — including the nature and authenticity of the communication transcript — believes the entire log is fake.

Capt. Jason D. Neubauer, who retired from the US Coast Guard and serves as chairman of the Marine Board of Investigation, said his investigation team has found no evidence that those on board the Titan knew a fatal implosion was about to occur.

“I’m confident it’s a false transcript … it was made up,” he said, as reported by the Times.
